Plasma display panel

Abstract

There is explained a plasma display panel that is capable of preventing discoloration of a substrate caused by migration of a metal bus electrode or metal paste's running down. A plasma display panel according to an embodiment of the present invention includes a transparent electrode; a metal bus electrode formed on the transparent electrode; and a black layer formed on a side surface of the transparent electrode and between the metal bus electrode and the transparent electrode.

What is claimed is:  
     
       1. A plasma display panel, comprising: 
       a transparent electrode;  
       a metal bus electrode formed on the transparent electrode; and  
       a black layer formed on a side surface of the transparent electrode and between the metal bus electrode and the transparent electrode.  
     
     
       2. The plasma display panel according to  claim 1 , wherein an area of the black layer is 1.5 times as big as an area of the metal bus electrode. 
     
     
       3. The plasma display panel according to  claim 1 , wherein the metal bus electrode includes silver Ag. 
     
     
       4. The plasma display panel according to  claim 1 , wherein the black layer is formed on an outer upper surface of the transparent electrode located an outer side of a discharge cell. 
     
     
       5. The plasma display panel according to  claim 1 , wherein an outer edge of the metal bus electrode is aligned to an outer edge of the transparent electrode located at an outer side of a discharge cell. 
     
     
       6. A plasma display panel having an upper substrate and a lower substrate sealed a discharge gas injected into a discharge space of the inside thereof, comprising: 
       a transparent electrode formed on the upper substrate;  
       a metal bus electrode aligned to one side edge of the transparent electrode; and  
       a black layer formed between the transparent electrode and the metal bus electrode and on a side surface of the metal bus electrode.  
     
     
       7. The plasma display panel according to  claim 6 , wherein an area of the black layer is 1.5 times as big as an area of the metal bus electrode. 
     
     
       8. The plasma display panel according to  claim 6 , wherein the metal bus electrode includes silver Ag. 
     
     
       9. The plasma display panel according to  claim 6 , wherein the black layer is formed on an outer upper surface of the transparent electrode located an outer side of a discharge cell. 
     
     
       10. The plasma display panel according to  claim 6 , wherein an outer edge of the metal bus electrode is aligned to an outer edge of the transparent electrode located at an outer side of a discharge cell.
